DAVID D. OGILVIE, 0F LEE, NEVADA.

T o all whom it may concern:

|Be it known that I, DAVID D. OGrLvrE, a citizen of the United States,and a resident of Lee, in the county of Elko and State of Nevada, haveinvented a new and Improved Guard, of which the following is a full,clear, and exact description.

The invention relates to guards as are employed in certain classes offarming inachinery, such, for example, as mowers, reapers, headers,etc., and has for its object to provide a guard construction in whichthe ledger plates are easily removed and assembled with the guardfingers, and, when in operative position, are firmly held.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views. y

Figure 1 is a section on the line 1 1 of Fig. 2, showing a guardconstructed in accordance with my invention; Fig. 2 is a plan of theguard; Fig. 3 is an inverted plan -of one of the guard plates; Fig. 4tis a rear edge view of the same; and Fig. 5 is a section on the line 5-5ot' Fig. 2 with the ledger plate removed.

For convenience of illustration I have shown the guard fingers 5, asconstructed in accordance with my invention, applied to the usualfinger-bar 6, to which each is secured by a bolt 7, which also securesthe guide-plate 8 and the guide-clip 9 arranged at the top of the bar.The intermediate portion of each guard finger is constructed with a flathorizontal seat 10 for a ledgerplate 11, the latter having a lug 12secured to its under side adjacent to the rear edge of the plate,preferably dove-tailed and received in a corresponding way formed on thelongitudinal center of the finger below the seat 10, the said wayleading into a recess 13 of the finger, having a pocket 13a providedwith a downwardly and outwardlyinclined or curved wall with which thereduced outer end 15 of the ledger-plate 11 engages. The ledger-plate ismade relatively wider than is customary, and when it is in operativeposition it is engaged at opposite sides adjacent to its rear edge byupwardlyextending lugs or projections 16, rigidly formed on the guardfinger, the lugs of adjacent fingers abutting, as shown in Fig. 2, whenthe several fingers are assembled on the finger-bar.

Specification of Letters Patent.

Application filed October 22, 1909.

Patented Sept. 13, 1910.

Serial No. 524,040.

The ledger-plate is provided with an aperture 14 which extends into thelug 12 and serves as means for engaging a special tool, as shown indotted outline in Fig. 1, for driving the plate up to place and removingit from the finger. lVhen the plate is as- Isembled with the guardfinger', it is held in place not only by the lug 12 but also by theprojections 1G and the reduced end or projection 15, the latter byreason of its particular engagement with the 'wall of the pocket 13,tending to force the forward portion of the plate downwardly and bind itto its seat, as also bind the lug 12 in the dovetailed way. Each finger1s provided with the usual rearwardly-extended guard 17 of taperingform, overhanging the ledger-plate, and has smooth side edges.

Having thus described my invention, I claim as new'and desire to secureby Letters Patent:

1. The combination of a guard finger having a pocket at its forward endprovided with a downwardly and outwardly-inclined wall, and aledger-plate seated on and slidably engaged with the guard finger', withthe end of the plate passing into and engaging the said downwardly andontwardly-inehned wall, forcing the plate to its seat.

2. The combination of a guard finger having upwardly-extending lugs andprovided with a pocket arranged in advance of said lugs, said guardfinger having a way, and a ledger-plate seating on the finger andengaged at opposite sides adjacent to its rear edge by said lugs andhaving a lug secured to its under side slidably received in the way ofthe finger, with the forward end of the plate engaging the wall of thesaid pocket, forcing the plate to its seat.

3. The combination of a guard finger', and a ledger plate removablyseated on the finger, the forward end portion of the plate engaging witha portion of the finger, with the said engaging portions arranged andconstructed to cause the plate to be depressed to its seat when the saidplate is forced forwardly.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

DAVID D. OGILVIE.
